4.4 Functions
The SmartBoard provides a wide range of functions that can be accessed via sym-
bols from the main menu. The chapters below describe the various functions.
The following rules apply:
• If a system is not available and no information can be retrieved from it, the cor-
responding menu symbol is not displayed.
• When the vehicle is at a standstill, the values that were last saved are displayed.
These may deviate from the actual values (e. g. the tyre pressure if a leak is
present).
For an overview of which functions are available in combination with Trailer EBS D
or E, see chapter 3.2 "System prerequisites", page 11.

4.4.1 Odometer Status
The odometer reading from the Trailer EBS and the SmartBoard is displayed in this
functional group.
Notation Description Note
Odometer (internal
odometer Smart-
Board)
The SmartBoard determines
the mileage/kilometrage
directly from the ABS sen-
sor signal.
• The option is only displayed after the SmartBoard has
detected that an ABS sensor is available.
• The distance counter functions even when the ISO con-
nection is not plugged in.
• Differences between Trailer EBS odometer and the in-
ternal odometer occur due to:
Driving without the ISO plug connection (TEBS not oper-
ating, SmartBoard supplied by battery).
Different tyre sizes and going around corners (TEBS
computes the average wheel speed, the SmartBoard
only records sensor c).
• If the tyre settings stored in the SmartBoard are inconsis-
tent with those of the TEBS, an exclamation mark <!> is
displayed in the odometer bar.
Mileage/Kilometrage The total mile-
age/kilometrage is recorded
by the Trailer EBS modula-
tor.
Record since the Trailer EBS system start-up.
Trip EBS Kilometre count with ISO
supply connected.
Can be reset via the diagnostic software.
